It has naturalised in parts of California, USA and is listed as an invasive alien species in Portugal.

The etymological root of the binomial name Acacia is derived from the Greek akis ‘pointed object’ in reference to the thorny nature of a number of plants within this genus. Retinodes is derived from the Greek rhetine ‘resin of the pine’ and the suffix oides meaning ‘like’.
